Is a t3/t4 to big for a stock y7- even if its got good exhaust flow-

 

 

if you searched...i just put in a t3/o4e ball bearing into my stock y8 this weekend. the power diff from my 42/48 was major. it lagged a bit in the low rpms of 1st gear but it spooled by 4k. it shouldnt be too much diff from yours...give or take 1k for yours not being bb. in 2nd i just spun out....too much boost...my 195/14's couldnt handle it. o yeah...mine was a 50 trim a/r .63. theres more boost on top and its a bit more consistent. i love it.

 

well what kinda t3/t4 are you talkin about?

theres a bunch of guys on hear runnin the 50 trim and seem to love it
